First of all you have to get the ip address of your connection. How do you do that?

See the internet icon in the taskbar. Right click that an choose status, and then choose support. here you ip would be written, it would be something like. 192.168.1.* . Note this.

2. Now open, 192.168.1.1, enter your username and password.

3. Go to advanced and then choose NAT.

4. From here choose the virtual circuit as PPoV7. Doing this would make DMZ and Virtual Server appear on the page. Choose DMZ.

5. In DMZ, select enabled and then enter that ip which you noted before. Choose Save. and then exit the browser.

6. If everything goes as planned, all your ports should now be open i.e enter any port in utorrent and it should be open and receiving connections.

This solved my problem. I hope it solves everyone else's

Other method:
1. open modem page
2. go to Advanced
3. Click NAT(on left)
4. select Virtual server
5. enter ip address and port no.
6. Click (save on botttom)

You are **DONE**
